My go-to test strip. One bottle lasts a long time.
I use this to check my swim spa water. I've come to trust it more than several other I've tried.
Accurately measures my spa chemical balance.
Never tried this type of test strips before and not sure I will buy them again. I can never get the ph patch to match up with any of the indicators on the container. Not sure what is wrong. I have another brand of test strip and it indicates my ph is too high, but the AquaChek strips are not even close to the correct color, either high or low for the ph patch.
